Description

CROSS REFERENCE TO RELATED APPLICATION

This non-provisional patent application claims priority under 35 U.S.C. § 119 from Chinese Patent Application No. 202111062644.X filed on Sep. 10, 2021, the entire content of which is incorporated herein by reference.

TECHNICAL FIELD

The disclosure relates to game controller technology, in particular to a joystick device and a handle using the joystick device.

BACKGROUND

Joystick device is one of common input devices, that is, the so-called 3D joystick, which is mainly used in electronic products such as game controllers. The joystick device mainly includes a stick and two rotating arms (an upper rotating arm and a lower rotating arm). The stick is stirred to drives the two rotating arm to operate a potentiometer regulator module to output a specific resistance value.
The typical joystick device commonly includes a brush, a circuit board, and a carbon film set on the circuit board. The brushes moves on the carbon film under an external force to generate different resistance values by the circuit board, and then different electronic signals are generated according to the different resistance values. The electric signals are capable of controlling the joystick device to control different directions. However, the method of adjusting the joystick device by a contact between the brush and the carbon film generally has the following disadvantages: if the metal with greater elasticity is used as the brush, the brush wears out quickly and the service life is short. If the metal with less elasticity is used as the electric brush, when brushing, a problem of poor contact and failure between the brush and the carbon film will easily occur; otherwise, if a high-hardness carbon film is used, the brush wears out quickly and will produce greater electrical noise, otherwise, if a low-hardness carbon film is used, the surface layer of the carbon film will soon be rubbed out of the carbon powder by the electric brush, and the carbon powder will stick to the electric brush, which affects the electrical performance of the electric brush and causes the joystick device to malfunction. Therefore, such joystick devices generally have short service life and poor performance defects, which eventually lead to the problem of “drift” during the game by gamers.

SUMMARY

In order to solve the above problems, a joystick device and a handle, which adopts Hall effect design, has the advantages of high control accuracy, stable output signal, long service life, etc., and can completely solve the “drift” of game players during the game problem.
In a first respect, a joystick device is provided and the joystick device includes a housing, a joystick assembly, a reset assembly, a translation assembly and a circuit board the joystick assembly, the reset assembly, the translation assembly and the circuit board are located in housing. The joystick assembly is capable of swinging in a first direction and a second direction perpendicular to each other; the reset assembly is configured to reset the joystick assembly after the joystick assembly swings; the translation assembly translates to left-right or forward-backward according to swing of the joystick assembly in the first direction or swing of the the joystick assembly in the second direction respectively, a magnetic element is fixed on the translation assembly. A magnetic induction element is fixed on the circuit board, the magnetic induction element generates an output that changes with the movement of the translation assembly.
In a first respect, a handle is provided and the handle includes the joystick assembly described above.
In this disclosure, the swing of the joystick assembly in the first direction and the second direction is converted into the movement of left-right translation and forward-backward translation through the translation assembly. Since the magnetic element is fixed on the translation assembly, the magnetic induction element is fixed on the circuit board to generate two electrical signal outputs by detecting the translation amount of the movement in the same plane in the two directions. The structure with translational displacement can achieve higher accuracy, so the joystick device has the advantages of high control accuracy, high sensitivity, stable output signal, long service life, etc. In addition, there is no frictional contact between the translation assembly and the magnetic induction element, which improves the service life and can completely solve the problem of “drift” during the game of game players.
